Mood, Th-1/Th-2 cytokine profile, and autonomic activity in older adults with acute/decompensated heart failure: preliminary observations.
In order to assess the relationships among mood, peripheral autonomic output and circulating immunoinflammatory mediators in older individuals with decompensated heart failure (CHF), 20 consecutive patients (78+/-7 years, 35% women) admitted to the coronary care unit with a clinical diagnosis of acute/decompensated CHF of coronary origin were examined. Mood was evaluated by the 21-item Hamilton Depression Scale (HAM-D). Four patients met the criteria for major depression. Heart rate variability (HRV) analysis and the levels of tumour necrosis factor (TNF)-alpha, interferon (IFN)-gamma, interleukin (IL)-2, IL-4, IL-6 and IL-10 were measured within 24-72 h of admission. A significant positive relationship between score in HAM-D and serum IL-6 levels was detected with a similar trend as far as IL-2 levels. Circulating IL-2 levels were strongly associated with the HRV L/H quotient, an index of increased sympathetic and/or decreased parasympathetic thoracic activity. A negative correlation between vagal activity (as assessed by HRV) and IL-4 occurred. Neither TNF-alpha nor IL-10 were detectable in this group of elderly patients. The results add to the concept that mood and autonomic unbalance are associated with increased systemic inflammation in old patients with decompensated CHF, a potential mechanism for mood-related worsened prognosis of heart failure at an advanced age.
